A vulnerability was discovered and corrected in gimp:

Multiple integer overflows in the load_image function in file-pcx.c in
the Personal Computer Exchange (PCX) plugin in GIMP 2.6.x and earlier
allow remote attackers to cause a denial of service (application
crash) or possibly execute arbitrary code via a crafted PCX image
that triggers a heap-based buffer overflow (CVE-2011-1178).
